Buffering device for online shearing of multi-channel aluminum alloy flat pipe

The utility model relates to a buffering device for on-line shearing of a multi-duct aluminum alloy flat pipe, which comprises a material guide roller group, a movable roller and a driving part, the material guide roller group is arranged between a reel and a shearing device and forms a transmission path for transmitting the flat pipe, the transmission path is also provided with a buffering area for buffering the flat pipe, and the movable roller is arranged in the buffering area. The movable roller is pressed on the flat pipe and enables the flat pipe to pass through the buffer area, and the driving part drives the movable roller to move back and forth in the buffer area in the extension direction of the buffer area. According to the utility model, the buffer area is arranged on the flat pipe transmission path, so that when the front section of flat pipe is cut in a pause manner, the rear section of redundant flat pipe is continuously transmitted and cached in the buffer area, and online non-stop cutting is
